| 摘 要： | 目的：探讨一氧化氮（ＮＯ）及氧自由基（ＯＦＲ）在新生儿缺氧缺血性脑病（ＨＩＥ）中的作用及意义。方法：取正常及ＨＩＥ急性期新生儿的静脉血制备成血浆，采用硝酸还原酶法测定ＮＯ的含量，用化学比色法测定ＭＤＡ的含量及ＳＯＤ的活力，用ＥＬＩＳＡ法测定ＮＳＥ水平。结果：ＨＩＥ急性期新生儿血浆ＮＯ、ＭＤＡ及ＮＳＥ水平较正常对照组新生儿均明显增高（均Ｐ＜０．０１）；而ＳＯＤ活力则明显降低（Ｐ＜０．０１）。结论：ＮＯ和ＯＦＲ与新生儿ＨＩＥ的发病机制有关。

| Abstract: | Objective:To study the effects of NO and OFR(oxygen free radical) in the neonates with hypoxic ischemic encephalopathy (HIE).Methods:Two groups of neonates were prepared, namely:① normally control group; ② HIE acute group.NO,MDA(malonyldialdehyde),SOD(superoxide dismutase) and NSE(neuron specific enolase) in the plasma were measured.Results:Compared with control group,the plasma NO,MDA and NSE levels increased significantly (P<0.01),SOD activity decreased significantly (P<0.01) in HIE acute group.Conclusion:NO and OFR are related to pathogenesis of HIE in the neonates. |
